Add additional camera presets
You just need the dimensions of the sensor.

Put those on the sensor width or height.

Then use the plus button (+) on the right of the preset to create a new one, and name it whatever you wish. 

To delete the presets you don't need, use the minus button.

Presets are a .py file located in the Scripts folder within the blender progra's folder. In windows they would be in

C:\Program Files\Blender Foundation\Blender\2.78\scripts\presets\camera.

As an example, this is the preset for a Full Frame camera:

Full_Frame_35mm_Camera.py

import bpy

bpy.context.camera.sensor_width = 36

bpy.context.camera.sensor_height = 24

bpy.context.camera.sensor_fit = 'HORIZONTAL'
